Acrobat Pro 7 opens Outlook when attaching PDF to email when TB is default?

I used Acrobat Pro 7 all day every day to create PDFs which I then click the email link in Acrobat and attach it to a message using Thunderbird. This all works fine with Thunderbird until I install Outlook. I've avoided having Outlook on my system for this reason, but am forced to in order to be able to sync my Blackberry. I have made certain that the default email client on my Vista 32bit Ultimate Edition PC is set to Thunderbird. No other program or email links do this - just Acrobat.

 

Thank you for your reply!! I had already gone through every preference I could find in Acrobat and could not find anything where I could specify one client over another.

I went back into the Windows default programs settings and when to the custom radio button and reset everything to Thunderbird (even though it already shows TB as the default) and then applied it and it worked! I have tried this numerous times by going to "Default Programs" and then choosing "Set Default Programs" and then choosing TB in the list and setting it as default, other times "choosing defaults for this program" and then ensuring that everything is checked for TB. It always shows TB as the default program, never Outlook (even after just installing Outlook). But last night I instead chose "Set Program Access & Computer Defaults" and then "Custom" and then I went down and changed the radio button to TB and hit OK. This, for some strange reason, made the difference. I've even rebooted and it still works.

Still confused, but relieved the problem is solved (at least for now).

 

As far as I know the Custom settings are the only ones which take care of problems like yours, unless, in this case, a website is hard coded to use a Microsoft program.
